Dear SEC,

I’m writing to support the conversion of Grayscale Bitcoin Trust (Symbol: GBTC), currently the world’s largest Bitcoin fund, to the first Spot Bitcoin ETF in the United States.

*As an Environmental Biologist in Sacramento California,  I understand the thesis of Bitcoin Mining actually being the secret weapon to combating climate change by being a reliable customer of energy that will pay 3X what rate payers pay. This reduces to the payback time for renewable energy projects that partner with Bitcoin mining companies.

A spot ETF opens the door to institutional money into the space, accelerating the adoption of renewable energy, and will propel us forward into the future. *

Sincerely,
*** Michael Scaffidi ***
